# Mira as a backend for the OpenTelemetry Demo.
#
# Copy this over `src/otel-collector/otelcol-config-extras.yml` in a demo
# checkout. That file is the demo's documented seam for exactly this — it is
# empty upstream and always loaded last — so nothing else in the demo is
# touched.
#
# The Collector *replaces* arrays across config files rather than appending to
# them, so every pipeline below repeats the upstream exporters it wants to keep.
# Getting this wrong silently unhooks the demo's own backends, which then looks
# like Mira broke them.
#
# Names are `otlp_grpc` / `otlp_http`: the demo pins collector-contrib 0.159,
# where the old `otlp` / `otlphttp` spellings are deprecated aliases. Both work;
# docs/e2e/otelcol.yaml uses the old ones because it runs against `:latest` and
# they are the pair that works on every version.

      # Repeated verbatim from otelcol-config.yml. The demo's metrics pipeline
      # is the interesting one: alongside OTLP from the services it carries
      # `host_metrics`, `docker_stats`, `nginx`, `redis`, `postgresql` and a
      # Prometheus scrape, which is a far wider spread of instrument shapes —
      # including exponential histograms — than any generator produces.

    # `profiles` is deliberately not routed here. OTLP profiles are a separate
    # signal with its own protobuf, Mira does not accept it, and adding it to
    # this pipeline would make the collector log a permanent export failure
    # every few seconds for a signal nobody asked Mira to store.
